Randy Klein is a metahuman with the ability to transform into a shadow-like form in the CW Television series Smallville. He appeared as the secondary antagonist in the Season 8 episode "Prey".
He was portrayed by Tyler Johnston.
At some point, Randy Klein was exposed to Kryptonite and gained metahuman abilities to become a shadow with flight, super speed and strength and intangibility.
Randy had joined a therapy group for kryptonite infected metahumans at the Isis Foundation hosted by Chloe Sullivan. Randy said the group was good for him because he didn't feel alone. Another member Mary Pierson insulted him and told them how people do not like the meteor-infected and thought they were scum. Around this same time, a mysterious serial killer was stalking the streets of Metropolis. Mary had been killed and the rest of the counseling group including Randy held a vigil at the place where she was killed.
Having always wanted that kind of attention, Randy set himself up as a copycat. He attacked EMT Davis Bloome and Daily Planet photographer Henry James Olsen in an alley. Clark Kent arrived and saw Davis stumbling out covered in blood and injured. Clark asks where Jimmy is but Davis is pulled away by a fast-moving, smoky blur. Clark tried to track the two of them down and sees the blur choking Davis, but it flees at the sight of Clark. Jimmy comes out of hiding and they look for the creature together. When Clark's back was turned, the creature pulled Jimmy away behind some dumpsters, where another victim lays. Clark sees the creature attack Jimmy and threw a large tire at him with incredible force and speed. Changing from his shadow form, the creature was revealed to be Randy.
Randy was stopped by Clark Kent and after he was knocked out, Jimmy shot his photo. He was taken into custody. After he was locked up, Randy was approached by Eva Greer, who noted that Randy had an alibi for at least one of the murders that he claimed to be behind. Something the police would soon uncover. Greer then gave Randy an offer to join a team of people like him.
